Why you ask? Cause this...
He is using a metal lathe, and I have one, but permanently destroyed ways ain't happening.
Plus might be easier to attach to my radial arm drill.
I'm thinking that partly finishing with diamond charged hardwood cups may work, after all I would have a wood lathe.
I am also thinking heck with balls, how about ornate stone columns? Finish flats with countertop tools?
What y'all think?

Getting read to do the same thing. I have my wood lathe and a core drill I set up to raise higher. This is the same principle used to make wood beads. Just got in the drill bits to drill the stones to hold rough stones in the lathe. The core driller will do up to 10" core bits the lathe can turn up to 12".

I'm wondering if being able to run a slower spindle speed on the lathe for larger stuff may be helpful. As soon as I get around to making a mount for it I want to put one of my 2 speed swamp cooler motors on the drill press to slow it down more for larger bits. |

Next trip north, swing by and say hi. They might have a spot for ya. www.google.com/maps/@44.2658692,-109.1431654,805m/data=!3m1!1e3 URL works for me but not for ProBoards, apparently. Looks like you'll have to copy & paste the whole string. |

One thing I thought was odd was that he put the hole cutter on the drill press, but he was not rotating the hole cutter. When they make small wooden spheres they spin the block of wood on the wood lathe then use a spinning cutting cup to cut in to the block of wood. That is why I got the coring machine and set it up to be able to raise it above the wood lathe.
I was going to core the rocks first, then use modified PVC cups to hold the cores, but saw another video with a better way. He was drilling holes in two sides of a rough stone. Then he glued dowels in the ends the insert in the lathe, then used a hole saw spinning with a drill to cut the ball shape. I figured on the larger stones instead of gluing the dowels in that I would instead drill a hole through the dowels with a drill press, then cut a cross in to the ends of the dowel. The crossed end inserted in to the hole drilled in the stone, then a screw or lag bolt screwed in the hole to expand the crossed part of the wood dowel. This will lock the dowel in place making it easier to remove afterward, as well as provide extra support to the dowel.
Then the dowels inserted in to the chucks. I have a larger 3/4" bearing chuck on order for the lathe tail stock so I can use larger dowels. At some point I want to add a jawed chuck to the tail stock to allow even larger dowels for larger stones. The stone will have to be rotated by hand first to make sure it clears everything, and I can cut off anything that does not.
Then I plan to spin the stone with the wood lathe, then cut the stone with the core drill while it is spinning.
I will have to build a splash guard for the lathe motor to keep water from the core drill from splashing in to the lathe motor, which will be pretty easy. Have all sorts of plexiglass I can use for that.

Interesting! I have a metal lathe that I don't use that I haven't had any luck selling.

Rockoonz it's one of the little 6" Craftsman made by Atlas. Mine is the Atlas 618 so same thing. I keep my eyes open for a 10" or 12" that I can run single phase, would be nice to have 1" pass through so I could thread longer shafts, maybe even a gearbox instead of the change gears. I assume you have the change gears too, don't know if they ever put a gearbox on those. |

Yeah I think it is the change gears. I've really not done much with it at all. It's something I inherited when my dad passed last year. I used his wood lathe a lot more!
